Samsung’s Galaxy Note 10 will retain the variable aperture camera feature that was first introduced with the Galaxy S9 series. Having such a feature determines and changes the amount of light that can enter the lens, and this also depends on the lightning conditions. Since two years now, Samsung has implemented a two-stage variable aperture mode, with the widest aperture on the Galaxy S10 series having a value of F/1.5. With the Galaxy Note 10, things are rumored to be a little different, but can this feature actually help out customers who want a capable camera configuration with their expensive smartphone purchase?

The news comes from well-known tipster Ice Universe, who states that Samsung’s Chinese engineers have reportedly said that the Galaxy Note 10 will ship with a three-stage variable aperture. It’s not stated if the less expensive version of the Note 10 will also come with this feature, but if Samsung incorporated a variable aperture on the Galaxy S10e, it will most likely port the same feature on the more cheaper flagship phablet.
